Problem: players hear only the master-client's sounds

Hello, dear friends!

I have creates voice communication between players in the room as in documentation. But I find out several problems.

1) A problem #1:
After applications' launch the first player doesn't hear in general whose sounds. All others (which have started after master-client) hear only the first (only master-client). Why it so, I can't understand...

2) Problem #2:
I would like that each player would hear sounds of others like usual AudioSource. That is at a long distance from a sound source the player shouldn't hear a sound of other player. And vice versa - at approach to other player my player has to hear how the loudness of other player increases. Whether it is possible to make it?

3) Problem #3:
When changing the audioclip at the PhotonVoiceRecorder component this component continues to broadcast the first audioclip which was we will appoint to it at start of the application. How it is possible to solve this problem?

4) Main task:
The main task for me is that each player heard a voice or playing of the audioclip of all other players. At the same time I would like that the sound at each player was heard taking distance of sources of a sound of all other players.

Here in the pictures is my settings and a script for understanding:

In the picture with three applications top application is Master-client (runned first). Apparently on the picture, at the master-client the sound from other players is false. At the same time at other players their audioclips are played, but AudioDetector either shows a false, or isn't created (null) at all:
